BOSS Audio CH3220 3.5 Inch Car Door Speakers — 140W Max, 4Ω, 2-Way Coaxial (Sold in Pairs)

Compact Power for Everyday Driving

Upgrade your car’s sound with the BOSS Audio CH3220 Chaos Series 3.5 Inch Car Door Speakers. Designed for tight door spaces, these coaxial 2‑way full‑range speakers deliver a more pronounced midrange and clearer highs without demanding a major overhaul of your existing setup. With a peak power rating of 140 watts per pair and a 4 ohm impedance, they’re built to work smoothly with a wide range of head units and amplifiers.

Key specifications help you gauge what you’ll hear on the road: a broad frequency response from 100 Hz to 18 kHz, a sensitivity of 88 dB @ 1 watt/1 meter, and a compact footprint (dimensions 4.7 x 3.4 x 2 inches; mounting depth 1.5 inches). The combination of a poly injection cone and rubber surround is designed to resist wear and road vibration, while the 1 inch voice coil and 1 inch polyimide tweeter work together to reproduce vocals and higher frequencies with clarity.

Real‑world listening notes

In daily driving you may notice crisper vocals, more defined instrumental details, and an overall sense of balance across tracks that span rock, pop, and acoustic genres. The CH3220’s wide yet controlled high end helps highs feel bright without becoming piercing, while the midrange remains clear enough to keep dialogue and melodies intelligible on crowded commutes.

• Sensitivity: 88 dB @ 1W/1m enables more audible playback from standard head units
• Durable build: poly injection cone with rubber surround supports long‑term performance

Consider these speakers as a possible step toward a more engaging in‑car listening experience, especially for listeners who value mids and highs in compact speaker form factors.
